STRING FOR MUSICAL INSTRUMENTS.

Specification of Letters Patent.

Patented Sept. 3, 1918.

Application filed December 22, 1914. Serial No. 878,628.

To all whom it may conccr'm Be it known that I, AUcUsTn NICOLLE, a citizen of the French Republic, residing at Lyon, Rhone, in France, have invented certain new and useful Improvements in Strings for Musical Instruments, of which the following is a specification.

This invention relates to improvements in strings for musical instruments such as pianowires and the like.

Spun strings have hitherto been made with a core of steel or gut and a covering made of copper, silver, or aluminum wire wound around this core. I

The present invention is for the purpose of further increasing the density of the string by using for the covering around the core a filament or wire of pure tungsten or of tungsten alloyed with other metals which would lessen its density to the least extent.

Tungsten which has a density of about 19 imparts high density to the string so that the quality of the sound produced is improved.

In order to render the tungsten more duetile or more easily workable it can be alloyed with other metals such as copper, silver or I tin which would give the greatest possible density.

For strings with double spun coverings two metal wires are employed either of the ame metal or of two different metals wound around the core. According to the invention a wire of pure tungsten is used or of an alloy of tungsten for the one covering wire, and the second covering wire is made of copper, silver, platinum, lead or the like.

Copies of this patent may be obtained for five cents taining different modifications in the density This double wire covering allows of ob- 40 and suppleness of strmgs.

To further explain the invention, reference is made to the accompanying drawing, which is an elevation on an enlarged scale of a string embodying my invention. The catgut string or elastic core is indicated at 1 and the tungsten-containing wire 2 is shown as wound around the core.

What I claim as my invention and desire to secure by Letters Patent of the United States is l. A string formusical instruments comprising a core of catgut, and a covering therefor composed of wire containing tungsten wound around the core.

2. A string for musical instruments c0mprising a core of catgut, and a covering therefor consisting of a wire made of an alloy of tungsten with a metal which approaches it in density and increases its ductility, said wire being wound around the core.

3. A string for musical instruments comprising an elastic core and a covering there for composed of a fine wire containing tung sten wound around the core.

In witness whereof I have signed this specification in the presence of two witnesses.

AUGUSTE NICOLLE.
